You haven't grasped the crux of the problem.
What you perceive as a financial problem stems from your thinking remaining within a framework. You haven't broken free from the constraints this framework places on your thinking.
There are many malicious attackers on this forum, so I don't want to go into a specific discussion about the JF-17 issue. I'll use another example to illustrate this problem.

This is a very common perforated steel sheet in our daily lives. Many processing plants are engaged in this business. The process is also very simple; you just need to buy finished steel sheets from the market, and then use a machine tool to punch holes according to the customer's requirements to start production and shipping.
If you think this is a good business, you'll start doing it too. However, after you delve deeper, you'll find that the market price of these perforated steel plates is lower than the price of the raw materials (steel plates).
If you still think about this problem with traditional thinking, you'll be stuck in a dead end, never able to figure it out. But that's China today. This phenomenon isn't limited to this field; it's happening simultaneously in many other areas.
If you use the same thinking to consider the future of the JF-17, you'll still encounter this dead end.
Regarding the JF-17 upgrade issue mentioned by PAF, this forum analyzed it a long time ago. The current development plan perfectly aligns with that analysis. You can check the relevant historical records.
